Improving Visual Audio-Pitch Discrimination

This study shows that the effects of an anodal stimulation on T3 with a cathodal stimulation on the right shoulder significantly boosted audio-pitch perception. The subjects were given bilateral anodal, cathodal, and “sham” (sham stimulation is a generic term to indicate an inactive form of stimulation) tDCS in a randomized counterbalanced order. The effects were staggering, with anodal stimulation the Random Gap Detection Test (RGDT) scores improved 22.5% while cathodal decreased it by 54.5%.
